Thermal head

Abstract

A thermal head is provided with first and second sets of parallel bar-shaped electrodes which are arranged in slightly spaced parallel planes and cross over one another. Individual crossing resistors are selectively energized to produce a heat generating dot which may be reproduced on a heat sensitive media.

What is claimed is: 
     
       1. A thermal head comprising, first bar-shaped heat generating resistors arranged in a first plane in a manner so as to be substantially parallel to one another; and   second bar-shaped heat generating resistors arranged in a second plane parallel to said first plane and disposed in a manner so as to be substantially parallel to one another;   said first bar-shaped heat generating resistors crossing over said second bar-shaped heat generating resistors to provide heat generating dots at the crossing points;   wherein said first and second bar-shaped resistors cross obliquely, such that crossing points of one line are offset from crossing points of an adjacent line.   
     
     
       2. A thermal head comprising, first bar-shaped heat generating resistors arranged in a first plane in a manner so as to be substantially parallel to one another; and   second bar-shaped heat generating resistors arranged in a second plane parallel to said first plane and disposed in a manner so as to be substantially parallel to one another;   said first bar-shaped heat generating resistors crossing over said second bar-shaped heat generating resistors to provide heat generating dots at the crossing points, said thermal head further including a substrate supporting one of said first and second bar-shaped resistors, and a protective layer overlying said substrate, and wherein the other of said first and second bar-shaped resistors are embedded in said protective layer.
